Solution Overview
Problem
Existing telescopic cameras in mobile phones cannot automatically rotate after being popped out, limiting the screen-to-body ratio without compromising image capturing functionality.
Innovation Solution
A camera assembly with a driving mechanism that converts a steering driving force into a linear driving force, allowing the camera module to reciprocate linearly and rotate, featuring a screw rod, sliding plate, and magnetic connectors to control the cooperation between driving forces and prevent simultaneous linear reciprocation and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a telescopic camera is used to increase screen-to-body ratio, then the screen area is improved, but the camera cannot automatically rotate after being popped out
Solution Approach 1:
The camera module is designed to be dynamically adjustable, transitioning from a fixed position to a rotatable position. The rotating shaft and transmission part enable the camera to rotate to different angles (e.g., 45 degrees) after being popped out, making the system adaptable to different shooting scenarios while maintaining the increased screen area benefit
2Adaptability or versatility
If a rotating mechanism is added to the telescopic camera, then the camera rotation capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the telescopic extension mechanism and the rotation mechanism into a single integrated system. The transmission part serves dual functions: it controls the camera's linear movement for telescopic extension and, through engagement with the first gear, controls the camera's rotation. This merging of functions reduces the number of separate mechanisms needed and simplifies the overall device complexity
Solution Approach 2:
The transmission part is designed as a universal component that performs multiple functions: it acts as both a linear actuator for telescopic movement and a rotational actuator when engaged with the gear system. This multi-functionality eliminates the need for separate mechanisms, thereby reducing device complexity while maintaining full rotation capability
3Adaptability or versatility
If a transmission mechanism is used to enable rotation, then the camera rotation is improved, but the manufacturing complexity increases
Solution Approach 1:
The transmission mechanism is segmented into distinct functional components: the transmission part for linear movement, the first gear for rotational engagement, and the rotating shaft for rotation execution. This segmentation allows each component to be manufactured independently using standard manufacturing processes, reducing overall manufacturing complexity while enabling the desired rotation capability

Implementation Method 1
a screw rod coaxially connected with the output shaft to enable the screw rod to rotate synchronously with the output shaft to transfer the steering driving force; and a sliding plate threadedly fitted with the screw rod to enable the sliding plate to reciprocate linearly along the rotating axis direction when the screw rod rotates
Implementation Method 2
